Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: white crystalline powder. Danger! Strong
oxidizer. Contact with other material may cause a fire.
Corrosive. Causes eye and skin burns. May be harmful if
swallowed. May cause severe respiratory tract
irritation with possible burns. May cause severe
digestive tract irritation with possible burns.
Target Organs: None known.
Potential Health Effects
Eye: Causes eye burns. May result in corneal injury.
May cause blepharitis (inflammation of the margins of
the eyelids).
Skin: Causes severe burns with delayed tissue
destruction.
Ingestion: May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns.
May cause perforation of the digestive tract. May be
harmful if swallowed.
Inhalation: Causes chemical burns to the respiratory
tract. Aspiration may lead to pulmonary edema. May
cause systemic effects. Causes corrosive action on the
mucous membranes.
Chronic: Prolonged or repeated skin contact may cause
dermatitis. Prolonged or repeated eye contact may cause
conjunctivitis. Effects may be delayed. Laboratory
experiments have resulted in mutagenic effects.
Section 4 - First Aid Measures
Eyes: Get medical aid immediately. Do NOT allow victim
to rub or keep eyes closed. Extensive irrigation with
water is required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush
skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Wash clothing
before reuse. Destroy contaminated shoes.
Ingestion: Do NOT induce vomiting. If victim is
conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person.
Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from
exposure and move to fresh air immediately. If
breathing is difficult, give oxygen. Do NOT use mouthto-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable
mechanical device such as a bag and a mask.
Notes to Physician: Treat symptomatically and
supportively.
Section 5 - Fire Fighting Measures
General Information: As in any fire, wear a selfcontained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with
combustible materials may cause a fire. During a fire,
irritating and highly toxic gases may be generated by
thermal decomposition or combustion. Use water spray to
keep fire-exposed containers cool. Use water with
caution and in flooding amounts. Contaminating or
mixing with foreign materials such as combustibles,
grease, and fuels can cause fire. Containers may
explode when heated.
Extinguishing Media: Use water spray to cool fireexposed containers. Contact professional fire-fighters
immediately. Cool containers with flooding quantities
of water until well after fire is out. For small fires,
do NOT use dry chemicals, carbon dioxide, halon or
foams. USE WATER ONLY. For large fires, flood fire area
with water from a distance.

NFPA Rating: (estimated) Health: 3; Flammability: 0;
Instability: 1; Special Hazard: OX
Section 6 - Accidental Release Measures
General Information: Use proper personal protective
equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place
into a suitable disposal container. Avoid runoff into
storm sewers and ditches which lead to waterways. Clean
up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty
conditions. Remove all sources of ignition. Provide
ventilation. Do not get water inside containers. Do not
use combustible materials such as paper towels to clean
up spill.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Use only
in a well-ventilated area. Minimize dust generation and
accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid contact
with heat, sparks and flame. Avoid contact with
clothing and other combustible materials. Do not ingest
or inhale. Discard contaminated shoes.
Storage: Keep away from heat, sparks, and flame. Keep
away from sources of ignition. Do not store near
combustible materials. Keep container closed when not
in use. Store in a tightly closed container. Store in a
cool, dry, well-ventilated area away from incompatible
substances. Keep away from acids.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Facilities storing or utilizing
this material should be equipped with an eyewash
facility and a safety shower. Use adequate ventilation
to keep airborne concentrations low.
